GERMANY SWITCH POINT FOR TUBULAR POSTAL SYSTEMS The present invention relates to a particuuarly simple tubular postal switch point, requiring very little space, and consists in the provision of a rotary part formed by an S- shaped curved blade provided with packing flanks and which is mountedrotatably in a cylindrical or conical seating, similar to the body of a tap in atap seating, in a casing forming the connection between the branching tube by meansof a neck member and a pivot member. In each position of through passage of the switch point the S-shaped part of the blade completes the casing so as to form a passage without obstruction whilst at the same time it forms with the casing and the flanks bearing there-on an airtight closure both for the tube through which the container is to pass and also'for the other tube or tubes through which the container is not to pass.

An application for patent for this invention wasfiled in Germany on June 23, 1926.

The invention will now be described by 7 way of example with reference to the ac companying drawing showing one example of construction. j The drawing shows in Fig. 1 a longitudinal section, and in Fig. 2 a cross-section of a switch point for two branching tubes. j

The tubes are adapted to be' connected to the openings?) and 0 of the casing d of the switch point. In the casing the two" passages are combined into a single passage 6. In the casing there is rotatably mounted by the neck bearing on and the foot pivot k an S-shapedblade W, which, as shown in the drawing, forms a closed passage for a con tainer in the direction of travel thereof. The position of the blade W as shown in the draw ing enables'a container to pass from b to e or vice versa whilst at the same time the portion of the casing'to which the other tube is connected at c, is closed in airtight manner from the through passage by'the central portion w and the flank portions w These latter parts constitute with the middle part w a body of rotation which moves in an airtight manner in the cylindrical portion 1 of the casing 03 in the same manner as thebody of Application filed March 14, 1929, Serial No. 346,876, and in Germany June 23, 1926.

a tap in a tap bearing, so that in every position of the blade W it forms a fluid-tight joint between d and Q02. A central rib e0 serves to strengthen the blade W.

The rotation of the blade is for example effected by means of a toothed wheel 2, located at the upper neck portion, with which is adapted to engage. for the purpose of rotation, a smaller driving Wheel passing through an opening 3 of the casing. It will be understood that the drive may also be effected by means of a chain or by other means, and if desired at the pivot end which in such a case would be formed as a shaft extending to the outside of the casing. If necessary the neck bearing and the pivot bearing may be formed of roller or ball bearings.

The invention is not limited to a twobranch switch point. The rotary body W i may be conical instead of cylindrical.
